Seven Spanish cities worked together to accelerate urban regeneration through inclusive retrofitting, energy innovation, and citizen participation. URBANEW focused on co-designing renovation strategies with residents, promoting bio-based construction, supporting vulnerable groups, and building local capacity. By aligning regulatory, financial, and social levers, the consortium created models for deep decarbonisation of the built environment designed for Southern European conditions. Cities involved: Barcelona, Madrid, Seville, Valencia, Vitoria-Gasteix, Valladolid, Zaragoza.
